4 Claims. (C1. 83-553) My invention relates to a device for cutting tabs on cards and ledger sheets or other similar arrangements.

An object of my invention is to provide a device which includes selective elements to provide means whereby projecting tabs can be cut on cards at any desired location.

A further object of my invention is to provide a device of this character which cuts the tabs and also shoulders on the cards by means "of simple settings.

With these and other objects in view, my invention consists in the construction, arrangement, and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth. pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure l is a side sectional elevation taken along the lines 11 of Figure 2 of my invention,

Figure 2 is a plan view of Figure 1,

Figure 3 is an enlarged sectional detail taken along the lines 3-3 of Figure 1,

Figure 4 is an enlarged plan view of a portion of the device,

Figure 5 is an enlarged detail of the setting arrangement, and

Figure 6 is a view of the finished card showing the various positions of the tabs that can be cut on the card by means of my device. 7

My invention contemplates the provision of a device which can be used in an otfice 'or other location and wherein ordinary cards can be readily and quickly out having record tabs formed on such cards for the usual indexing systems of the type usually having letters to indicate card classification, etc.

I have used the character 10 to designate a relatively large wheel having the radial spokes 11, the spokes 11 being attached to the hub 12, which hub is attached to the transverse shaft 13 which is journalled at 14 within the vertical walls 15. Attached to the shaft 13 are the end plates 16 and 17 having the projecting portions 18, and attached across the projecting portions 18 are the various blades 19 which are approximately radially positioned and are also slightly pitched, these blades being attached at 20 to the plate 16 and at 21 to the plate 17 whereby they will correspondingly be backwardly bent with the portions at 21 being ahead of the portions at 2% during rotation, thereby creating a travelling contact position during the full cutting action.

Formed in the blades 19 are the substantially semicircular cut-out portions 22, it being noted that these cut-out portions are spaced progressively toward the wheel 10 as these portions are provided in the various blades 19, the reason for which will be explained later.

I have further used the character 23 to indicate a fiat plate attached between the walls 15 and attached to this plate is a lower plate 24 to which is secured by means of the fiat head screws 25 a further hardened plate 26 having the shoulder portions 27 at either side thereof.

Attached to the forward edge of the plate 24 are the ite States Patent r Patented u ao, 1960 2 vertical fingers 28. The various blades 18 also include the cutout shoulder portions 29 which are adapted to register with the shoulder portions 27, these blades also including the small cavities 30 which are adapted to pass by and receive the fingers 27 when the device is used.

The screws 25 are made relatively loose to permit adjustment of the plate 24. p

Also journalled in the walls 15 is a further transverse shaft 31 to which is attached the spacing collar 32 and a further collar 33 to which collar 33 is attached at 34 the square-in-section adjusting bar 35, a lower corner of which is adapted to be received in any one of the five notches 36 in the keeper member 37 which is attached at 38 to one of the walls 15.

Welded to the shaft 31 as at 39 (see Figure 3) is a semi-cylindrical lug 350 which is adapted to abut at 36a against the plate 26 when the tab cutting operation is to be provided, and attached to the shaft 31 is a further hub 37a which is attached to an arm 38a which is attached at 39a to a helical spring 40 which is attached at 41 to a bracket 42 which is attached at 43 to another wall 15.

Attached by means of the bolts 44 to the plate 23 is a guide strip 45.

The character '46 indicates the base of the device which can be rested upon the top of a table indicated by the dotted lines character 47 with the wheel 10 being positioned at one side of the table,

The device is operated in the following manner. In assuming that a tab 43 is to be formed on the card 4% shown in Figure 6, the device is shown set for the position in Figures 1 and 2. As shown, the device will form either a tab in the No. 3 position on the card 49 or will form the No. 8 tab in the eighth position as shown by the dotted structure 5% in Figure 6. In first assuming that the No. 3 tab is to be formed, the wheel 10 is rotated in the direction of the arrow 51 (see Figure l) and it will be noted from Figure 2 that the opening 22 which is of the same configuration as the lug 35a will pass downwardly over the lug 35a and will cut out this particular tab or car, and also the descending shoulder portions 29 will out against the stationary shoulder portions 27 thereby cutting the shoulders 52 (see Figure 6) from the card. By raising the bar 35 against the spring pressure 4% the lower corner of the bar can be placed in any one of the notches 36 to correspondingly place the lug 35 at any selected position along the platform 26 so that as a result the tab can be formed at any desired position. As shown in Figure 2 it will be noted that the semi-circular cavities 22 are spaced in progressive lateral relation to each other to provide this result.

The blade which is marked 3-8 in Figure 1 will provide means for cutting the No. 3 tab 48 or the No. 8 tab 50 since by merely rotating the card about its length ened axis and keeping the lug 35a in the same position shown in Figure 2, the No. 8 position or the tab 50 will be formed. In this manner the tab or ear can be formed at any pre-selected position up to ten positions, it being understood, of course, that the machine could also be devised to provide any number of tabs and any design of shoulder and tab. The card 49 is placed against the fingers 28 and against the guide strip 45 before the cutting operation, and when it is desired to provide a tab at a new station, the lug 35a can be first swung out of the way. The large diameter wheel 10 provides means for applying maximum leverage to the arrangement, and if desired the space between the platforms 23 and 46 can be used for storing cards and the like. If it is desired to cut the shoulders 27 only, the lug 35a can be swung out of position, and this lug 35a is of course swung out of the way before each setting.

It will now be noted that I have provided the advantages mentioned in the objects of my invention with further advantages being apparent.

Some changes may be madein the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
